where {it:a} is a {it:real matrix} and {it:b} and {it:c} are matrices
of any type (as long as their types are the same).


{title:Description}

{pstd}
    {cmd:mm_cond()} is a matrix version of the scalar conditional operator
    (see {helpb m2_op_conditional:{bind:[M-2] op_conditional}}).

{pstd}
    When {it:a}, {it:b}, and {it:c} are not scalar, {cmd:mm_cond()} returns
    element-by-element results. {it:a}, {it:b}, and {it:c} are required to
    be r-conformable (see {helpb m6_glossary:{bind:[M-6] glossary}}).


{title:Remarks}

{pstd}
    None.
    

{title:Conformability}

{pstd}The arguments have to be r-conformable (see help
{helpb m6_glossary:{bind:[M-6] glossary}}). Returned is a matrix of
max(argument rows) rows and max(argument columns)
columns containing element-by-element calculated results.
